I would like to customize the rendering of a form field in the edit page from sonata admin bundle to include an applet that uses the text content of a field.
I know that I have to edit the configureFormFields
function in the admin class, but I need to know 3 things:
This form is used to export the currently displayed graphics scene to an image file or to a geometric scene description file suitable for use by one of several external renderers, which can produce a final image.
form_widget(form_view, variables)Renders the HTML widget of a given field. If you apply this to an entire form or collection of fields, each underlying form row will be rendered.
Found a solution
What i have done is:
Created a field type, lets call it myfieldType in myCompany\myBundle\Form\Type\myfieldType.php
namespace myCompany\myBundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
class myfieldType extends AbstractType
{
public function getParent()
{
return 'text';
}
public function getName()
{
return 'myfield';
}
}
Registered the Type in app/config/services.yml
myCompany.myBundle.form.type.myfield:
class: myCompany\myBundle\Form\Type\myfieldType
tags:
- { name: form.type, alias: myfield }
In my myentityAdmin class,
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->add('myfieldname', 'myfield')
...
}
and
public function getFormTheme() {
return array('myCompanymyBundle:Admin:myfield_edit.html.twig');
}
and the template :
{# src/mycompany/myBundle/Resources/views/Form/myfield_edit.html.twig #}
{% block myfield_widget %}
{% spaceless %}
{{ block('textarea_widget') }}
{% endspaceless %}
{% endblock %}
And now i can access the form field value by the twig variable "value" !
So easy... when you got it.
user1254498's solution won't work unless the block name prefix matches the name of the form type. At least with the last version of sonata admin bundle (2.2.12). In this case:
{# src/mycompany/myBundle/Resources/views/Form/myfield_edit.html.twig #}
{% block myfield_widget %}
{% spaceless %}
{{ block('textarea_widget') }}
{% endspaceless %}
{% endblock %}
And, regarding getFormTheme()
, you shoud return also the parent theme, otherwise you may break the whole style...
public function getFormTheme()
{
return array_merge(
parent::getFormTheme(), array(
'mycompanyBundle:Form:myfield_edit.html.twig')
);
}
Also, you can access the admin service in the twig template with the variable sonata_admin.admim
.
